h Be itknown that I, MARTIN LOGAN, acitizen of the Ilnited States, and a resident of New 3 York city,in the county of New Yorkand State 55 of New York, have invented a new and useful Y Imp'rovementin Stable-Drains,of which the g vand especially such as are adapted for'use in The'object of the invention is to eifectually" carry off from the floor of a stall or other place.

--whateverliquid'may fall thereon, whether it be the liquid excrement of animals or'other, .1; liquid, whereby the stable-fioor'may be kept 4 dry and in a proper sanitary condition. p,

Heretofore drains for stables have'been con- I structed comprising ajmetallic bed-plate pro 7 videdwith longitudinaldrain-channels alterzo nating with longitudinal tread-bars fitted in suitablerecesses. Such constructions are shown, in United States patents granted to me, No. 386,997, July 31, 188 8, and, No. 502,004, a July 25, 1893 Ithas been found in practice,

25 however,.-th'at the-drain-channels in the prior arrangemcntsfdid not in all cases efiectually carry off the liquid discharged in the drain.

Sometimes the drain-channels would become overcharged at various points along theirlength, owing not infrequently to neglect "on the part' of the stableman to, sweep out the drainchannels and entirely remove whatever matter tendedto clog them, and part of the liquid therefore often worked its way underthe tread-bar recesses, giving off offensive odors-and-keeping the floor more'or les's damp. My present invention is designed to'remedythese defects, and it does so in an eflicient Referring now to the drawings forming part of this specification, and 1' n which like letters of reference designate corresponding parts-a a drain and Fig. 3 is a longitudinalelevatiou partly in section, of such a drain; The stall A is provided with the -drain B.

tes to drains for stables,-

neath the tread-barsand there being no suitable way for it to escape became confined in manner and by simple and inexpensive means.-

This drain has a bed-plate 0, preferably made of iron and provided with longitudinal dramchannels c,alternating with tread-bar recesses d. Tread-bars D. fit snugly in-the recesses d, rising above the tops of. the recesses and channels, so as to make a corrugated top surface for the drain.

three, or more beneath each tread-bar, as desired. InFig. 2. there are three such ducts beneath each tread-bar. These ducts may be made entirely in the bed-plateC, within the recesses (has at c, or they may be made enselves, as at 0 orthey may be made. partly as at a These drain-ducts in whatever form made communicate with the drain-channels c,

so'as to receive the overflow liquid from the channels 0. The meansvof communication between the drain ducts, and drain channels preferably consist of a series of upright ducts Beneath the tread-bars are arranged drain-ducts, which may be one, two,

tirely inthe bottoms ofthe'tread-bars them- 1 i 6 5- in the bed-plate and partly in the tread-bars,

-e and cross-ducts 6', formed in the sides of the recesses d, as shown in the drawings Of course, if desired, these ducts e and a may both be formed inthe tread-bars, or the ducts e may be formed in the recesses and the ducts c be formed in'the tread-bars, or vice versa,

as will be readily understood. a

The channels cand ducts e c 0 lead on a gentle. decline to atrough 'E, arranged across the "foot of the drain, and this trough is closed 'by 'a cover E, made flush. with the top surface of the drain and floor, When. now the drainchannels. 0 become overcharged with liquid and the liquid rises toathe level of the ducts e, it mayescape through the ducts e and c c 0 into .the trough lE. Heretofore when the .liquid in the channels reached the edge of the tread-bars some of itworked its way beneath the tread-bars and remained .there because therewas no way for it to escape; It not only then emitted offensive odors, keeping the air impure, but was squeezed 0llti more or less when the horse or other animal-stepped upon the tread-bars, and operated-to keep the drain and the bedding on the floor damp,

It will be readily appreciated that the defects noted are effectually overcome by this in vention.

Of course various changes, which will readily suggest themselves to .any one skilled in -'the a rt', may be made without departing from thespirit of my invention. Forexample,sepa
